The UFO X is the latest in digital technology and high performance for TV reception in any mobile environment. It small diameter has the highest gain of any TV antenna in comparable size. The Majestic UFO X is the predecessor to the famous UFO which is over 10 years old in technology. The UFO X has a 30dB High Gain Amplifier built into the antenna which is a 58% increase in signal performance on the UFO. (For every 3dB Gain, the signal level doubles). This gives you a huge advantage over other TV antennas because there's no interference being induced when it receives a signal. The UFO X is also designed to be ground independent (does not need a ground plane or be grounded) to amplify the TV signal. This makes this antenna perfect for boats or any nonmetal roof.
